I have seen people grinding mobs til they are high leveled. They are never responding and and i've seen them there many days in a row, for example. The isle in Feralas there is a level 47 rogue that is grinding 40-41 wolves and a 40 or something mage grinding the raptors in dustwallow. Their behaviour just seems wierd in my eyes. The mage never targeted me, and never did something to me, except when a horde juped me and we were in combat right besides him, i polied him and ran of and he went back to normal again.
